1,1′-(2,2-Diphenylethene-1,1-diyl)bis(3,5-dimethyl-1H-pyrazol-2-ium) dichloride

IUCrData
The title compound, C24H26N42+·2Cl−, crystallizes in the triclinic space group P1. The ethene derivative is substituted by two phenyl groups in 2-position and two 3,5-dimethylpyrazolinium units in 1-position, which makes this alkene into a dication.

Kinetics and Thermodynamics of Alkene Complexation in d⁰ Metal−Alkyl−Alkene Complexes

, 2016
Alkene dissociation from the yttrium chelate Cp*2Y[η1,η2-CH2CH2CH2CHCH2] (7-on) became slow enough below −100 °C to be measured by dynamic 1H NMR spectroscopy [ΔG⧧(−110 °C) = 7.5 kcal mol-1, ΔH⧧ = 9.3 kcal mol-1]. Coalescence of the Cp* resonances of Cp*
